This thesis is a critical interpretation of a striking contention I call the Deformation Claim. The Deformation Claim alleges a deep deformation of beings in modernity. I extract such a claim from the work of Theodor W. Adorno and Martin Heidegger. My aim is to interpret and assess, in a more thorough manner than hitherto achieved, the respective elaborations of the Deformation Claim those thinkers provide. To that end, but mindful of challenges of interpretation and of charges even of complicity with the deformation at issue, I connect two lines of thought within each of my authors. I conjoin their accounts of the deformation of beings with what in their work answers to the determination of beings. An account of beings’ determination is an account of how beings, at a similarly ‘deep’ level to that of the Deformation Claim, are as they are.
